Better alternative would be that the MGs do more damage, just as they do in real life.
When COH 2 got released in 2013, The Maxim did 16dmg just as much as the conscript mosin, Grenadier Kar 98´s did 20dmg, and the MG 42 had 8dmg, do we really want to go back to old days where maxims would kill 1 model from a grenadier squad even before suppressing them, and grenadiers needed only 4 hits to drop a model from the enemy squad...
Buffing MG damage seems like the right thing to do, but me and my friend maxim spammed our way to TOP 30 2vs2 as Soviets and had over a 80 winstreak back in 2013, buffing damage would result in the same problem that the DSHK had when it got added to the game, 20dmg for it was too much since it murdered the small squads of Ostheer, so buffing AOE suppression is kinda the only fix to the blobbing issue
